I have noticed this problem since I started this game, basically overlapping shadows cause flickering and a unshaded outlining around the shadows that flicker.

I have tested with Gallium-Nine mesa17.2dev AMDGPU drivers and also CSMT. Both Wine2.9-staging.
I also disabled all graphics settings to see if it was a particular setting doing it but the problem persists.

If anyone else experiences this let me know here, its a bit annoying but since the game runs great with gallium-nine I'm just going to persist for now. Not sure if its a genuine bug or some issue with my setup, maybe if other people report similar issue then a bug can be submitted.
